The storage unit stores user information according to a specific device connected to an external network in advance. The control unit receives an execution instruction as an execution instruction of a job by a user indicated by the user information according to the specific device, if the execution instruction of the job is received from the specific device via the external network, and executes the job according to the execution instruction. ## Claims ### Claim 1 A method comprising: receiving, by an image forming device, remote job information from a server device, the remote job information comprising information associated with a user; authenticating, by the image forming device, the server device based on the remote job information; discarding, by the image forming device, the remote job information after determining that the server device is not authenticated; receiving, by the image forming device, an authentication setting; and executing, by the image forming device, a remote job according to the remote job information after determining that the authentication setting is not valid. ### Claim 2 (depends on 1) The method of claim 1, further comprising: reading, by the image forming device, remote user information after determining that the authentication setting is valid; determining, by the image forming device, if execution authority has been assigned to the user based on the information; and executing, by the image forming device, the remote job according to the remote job information after determining that the execution authority has been assigned to the user. ### Claim 3 (depends on 2) The method of claim 2, wherein the remote user information is read from a user information storage unit of the image forming device. ### Claim 4 (depends on 2) The method of claim 2, further comprising transmitting, by the image forming device, an indication to the server device after executing the remote job, the indication indicating that execution of the remote job has been completed. ### Claim 5 (depends on 4) The method of claim 4, further comprising recording, by the image forming device, log information after executing the remote job, the log information indicating execution of the remote job. ### Claim 6 (depends on 4) The method of claim 4, further comprising transmitting, by the image forming device, error information after determining that the execution authority has not been assigned to the user. ### Claim 7 (depends on 2) The method of claim 2, further comprising transmitting, by the image forming device, error information after determining that the execution authority has not been assigned to the user. ### Claim 8 (depends on 7) The method of claim 7, wherein the remote user information is read from a user information storage unit of the image forming device. ### Claim 9 (depends on 1) The method of claim 1, further comprising transmitting, by the image forming device, an indication to the server device after executing the remote job, the indication indicating that execution of the remote job has been completed. ### Claim 10 (depends on 1) The method of claim 1, further comprising recording, by the image forming device, log information after executing the remote job, the log information indicating execution of the remote job. ### Claim 11 A method comprising: receiving, by an image forming device, remote job information from a server device, the remote job information comprising information associated with a user; authenticating, by the image forming device, the server device based on the remote job information; discarding, by the image forming device, the remote job information after determining that the server device is not authenticated; reading, by the image forming device, remote user information; determining, by the image forming device, if execution authority has been assigned to the user based on the information; and executing, by the image forming device, a remote job according to the remote job information after determining that the execution authority has been assigned to the user. ### Claim 12 (depends on 11) The method of claim 11, wherein the remote user information is read from a user information storage unit of the image forming device. ### Claim 13 (depends on 12) The method of claim 12, further comprising recording, by the image forming device, log information after executing the remote job, the log information indicating execution of the remote job. ### Claim 14 (depends on 12) The method of claim 12, further comprising transmitting, by the image forming device, error information after determining that the execution authority has not been assigned to the user. ### Claim 15 (depends on 12) The method of claim 12, further comprising transmitting, by the image forming device, an indication to the server device after executing the remote job, the indication indicating that execution of the remote job has been completed. ### Claim 16 (depends on 15) The method of claim 15, further comprising recording, by the image forming device, log information after executing the remote job, the log information indicating execution of the remote job. ### Claim 17 (depends on 11) The method of claim 11, further comprising transmitting, by the image forming device, error information after determining that the execution authority has not been assigned to the user. ### Claim 18 A method comprising: receiving, by an image forming device, remote job information from a server device, the remote job information comprising information associated with a user; receiving, by the image forming device, an authentication setting; executing, by the image forming device, a remote job according to the remote job information after determining that the authentication setting is not valid; reading, by the image forming device, remote user information after determining that the authentication setting is valid; determining, by the image forming device, if execution authority has been assigned to the user based on the information; executing, by the image forming device, the remote job according to the remote job information after determining that the execution authority has been assigned to the user; and transmitting, by the image forming device, an indication to the server device after executing the remote job, the indication indicating that execution of the remote job has been completed. ### Claim 19 (depends on 18) The method of claim 18, further comprising: recording, by the image forming device, log information after executing the remote job, the log information indicating execution of the remote job; and transmitting, by the image forming device, error information after determining that the execution authority has not been assigned to the user; wherein the remote user information is read from a user information storage unit of the image forming device.
